COLLAPSlBLE-TUB E ATTACHM ENT.

EJPECIFICATION forming part of Letters Patent No. 648,981, dated May 8,1900.

Application filed July 8 1899. Serial No. 723,215. (No model.)

To all whom it may concern/.-

Be it known that I, FRANCIS A. NELsoN, a

,citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented a newand usefulCollapsible-Tube Attachment, of which the following is a specification.

My invention relates to an 'expunging tool or compressor to be used inconnection with compressible tubes or receptacles made of ductilematerial and which are generally used for dentifrices, surgicaldressings, ointments,

' oils, paints, or, in fact, any liquid material,

wherein the liquid is discharged through an opening by progressivelyfolding the closed end of the tube by a key; and the object thereof isto provide a holderor stand whereby the tube will be held in an uprightposition on a base and the contents can be expunged or dischargedwithout removing it therefrom.

With this object in view'my invention consists of a stand orbase havinga tube-receiv ing mouth for the reception of the closed end of the tubeand carrying means below the said mouth whereby the closed end of thetube can be folded upon itself step by step to discharge the liquidthrough the open end,which, as is well known,is usuallyhermeticallysealed by a screw-cap.

My invention further consists in so manipulating the closed end-of thetube that practically all of the contents will be discharged through theopening.

Myinvention further consists in certain details of construction andcombinations of parts, as will be fully disclosed in the followingdescription, recited in the claims, and illustrated in the drawingsforming a part of this specification, in which- Figure 1 is a detailperspective View of a holder, showing a tube held therein. Fig. 2 is atransverse section of the holder, illustrating the relative positions ofthe several parts. Fig. 3 is a perspective View of the holder. Fig. 4 isa similar view reversed. Fig. 5 is a detail perspective View of theclamping-rod for engaging the closed end of the tube, and Fig. 6 is aplan view of a blank for forming the holder.

Referring to the drawings by referencenumerals, 7 indicates the blank,which is formed of sheet metal cut out substantially rectangular in formand having the two diametrically-oppositely-arranged arms 8 and 9projecting from the sides of the blank intermediate its ends. After theblank is thus formed it is shaped up, as seen in the first four figures,to form. a base 10, from which extend the curved sides 11 and 12,converging at 13 to provide a contracted mouth or opening 14: andterminating in the diverging lips or guiding-lips 15 and 16. The armsare then bent up, and the inner surfaces thereof abut against the edgesof the blank proper to add rigidity to the sections thereof. Each arm isprovided with an opening or bearing 17 and 18, which is designed toreceive the rotatable split pin 20, to be more fully described asfollows: This pin comprises a head 21, from which extend the twooutwardly-projecting arms 22, contracted and then swelled at their freeends, so that when they are inserted in the bearings of the arms 8 and 9the spring in the arms will allow the swelled head to pass through, butwhen the contracted portion is reached the arms will spring apartsufficiently to hold the pin therein, but allow the same to be rotatedby turningthe head 21 with the hands.

The operation of my device is as follows: All the parts being assembled,the end of the tube being held vertically by the holder, the closed endwill lie between the arms 22, and by simply turning the pinprogressivelystep by step the contents of the tube will be successfully dischargedthrough the tube-opening, it of course being understood that the cap hasbeen first removed.

While I have described in detail what to me seems the cheapest and mostdesirable construction for accomplishing the result it is desired toattain, I would have it understood that I do not limit myself to theexact details of construction disclosed, but reserve the right to makesuch slight changes and alterations as would properly come within thescope of my invention without departing from the spirit thereof.

Having thus fully described myinvention, What I claim as new, and desireto secure by Letters-Patent of the United States, is-

1. In a collapsible-tube holder, the c0mbination, with a base formedfrom a cruciform piece of sheet metal, two of the arms of which are benttoward each other and having their tips bent outward to form ahopper-like opening therebetween, and the other arms are per- 5 foratedand bent up into engagement with the edges of the other arms at saidopenings and a split turning pin through said perforations in positionto grasp the closed end of the tube.

10 2. In a collapsible-tube holder, the combination, with a sheet-metalbase, the sides of which are bent toward each other and have their tipsbent outward to form a hopper-like opening and the ends are providedwith in- 15 tegral arms, perforated in alinement with FRANCIS A. NELSON.
